Specification of Letters Patent.

Patented Aug. 23, 1910.

Application filed February 17, 1910. Serial No. 544,439.

To all whom it may concern:

Be it known that I, FREDERICK WEHINGER, a citizen of the United States, residing at WVaterbury, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Stem- Winding and Stem-Setting Watches; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact clescription of the same, and which said drawings constitute part of this specification, and represent, in

Figure l a broken view in front elevation of my improved stem-winding and stemsetting watch with the dial removed and showing the parts of the winding and setting mechanism in their normal positions, or in other words, as adjusted for winding. Fig. 2 a broken view of the watch in rear elevation with a portion of the back movement-plate broken away, the parts being shown as adjusted for winding. Fig. 3 a broken view in rear elevation with the entire back movement-plate removed and the case in section to show the winding-and-setting mechanism as adjusted for setting. Fig. 4 a broken view in vertical section on the line ab of Fig. l on an enlarged scale. Fig. 5 a broken sectional view on the line ccl of Fig. 1, showing the screw by means of which the operating-lever is bodily moved toward and away from the stem. Fig. 6 a detached view of the operating-lever.

My invention relates to an improvement in that class of stem-winding and stem-setting watches in which the stem is pulled out for setting the watch, the object being to produce a watch of the character described which shall not only be effective and reliable, but constructed with particular reference to convenience in removing and restoring the stem without taking the movement out of its case or even removing the dial.

WVith these ends in view my invention consists in a stem-winding and stem-setting watch having its operating-lever bodily movable toward and away from the winding and setting stem which it couples with the movement.

My invention further consists in the combination with a laterally movable operatinglever, of a yoke carrying winding and setting wheels and provided with a stud, a

' locking-lever located between the front and back movement plates and engaging with said stud for moving the yoke into its setting position and formed with a lockingnotch receiving one end of said operatinglever for locking the said yoke in its setting position.

My invention further consists in certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claims.

In carrying out my invention as herein shown, I employ an operating-lever 2 mounted upon a stud 3 journaled in a bearing-hole 4: extending through the front movement-plate 5, through the bridge 6 and through the back movement-plate 7, the said stud having not only rocking movement in the said bearing-hole 4:, but also longitudinal movement therein. The rear end of the said stud 3 is counterbored and threaded for the reception of an operating-screw 8 by means of which the stud is bodily moved in the said bearing-hole 4 at a right angle to the plane of the Watch-movement. The upper end of the said lever 2 is bent rearwardly to form a hook or finger 9 which enters a circumferential coupling groove 10 in the longitudinally movable and rotatable winding-and-setting stem 11 which passes through a vertical hole or socket 12 in the bridge 6. WVhen the finger 9 is entered into the said groove 10 in the stem 11, the same is coupled, as it were, to the watch-movement though free to be rotated and to be longitudinally moved with respect thereto. But by reversing the screw 8 and at the same time applying forward pressure upon it, the operating-lever 2 is caused to back off, so to speak, by which is meant to move forward sufliciently to entirely clear its finger 9 from the groove 10 in the stem 11, whereby the same is uncoupled, as it were, from the watch-movement from which it may now be removed without disturbing the watch-movement or removing the dial, it being only necessary for the purpose specified to open the watch at the back so as to afford access to the screw 8. On the other hand, when the screw 8 is turned back to its place the operating-lever 2 is drawn rearward, and its finger 9 reentered into the groove 10 in the stem 11 which is thus recoupled with the watch-movement. I11 this bodily movement of the operating-lever at a right angle to the plane of the watchmovement its finger 9 is moved out of line with and into line with the hole or socket 12 in the bridge 6.

The outer or lower end of the lever 2 is formed with an inwardly turned finger 13 which extends over the upper edge of a fiat locking-lever 1e swiveled upon the adjacent pillar 15 of the movement, its upper edge being formed with a locking-notch 16 into which the said finger 13 snaps when the yoke 17 has been swung into its setting position by the pulling out of the stem 11, whereby the said yoke is held in its setting position during the operation of setting the watch without the necessity of maintaining outward draft upon the stem to overcome the effort of the spring 18 to turn it back into its normal or winding position in which it is normally maintained by the said spring. On the other hand, when the lever 2 is swung inward by the pushing inward of the stem 11, the finger 13 at the lower end of the lever is lifted out of the said notch 16 means of the said screw the lever may be permitting the spring 18 to restore the same to its winding position. A stud carried by the yoke 17 engages with the lower edge of the locking-lever 14: whereby the yoke is swung from its winding into its setting position.

I claim 1. In a stem-winding and stem-setting watch, the combination with the front and back movement plates thereof, of a bridge located between the said plates, a longitudinally movable and rotatable winding-andsetting stem, an operating-lever arranged to be bodily moved at a right angle to the planes of the said movement plates and to be positively connected with the said stem, a stud extending through the front movement-plate and the said bridge and having the said lever mounted upon its outer end, and a screw entering the inner end of the said stud through the said back movementplate for positively moving the said lever toward and away from the said stem, whereby the stem may be disconnected from the movement and connected therewith without removing the movement from its case.

2. In a stem-winding and stem-setting watch, the combination with a longitudinally movable and rotatable winding-and-setting stem, of an operating-lever normally coupled therewith, a stud on which the said lever is mounted, and an operating-screw entering the said stud and provided for moving the lever bodily in a plane at a, right angle to the plane of the watch-movement, whereby the said lever is connected with, and disconnected from the stem.

3. In a stem-winding and stem-setting watch, the combination with a longitudinally movable and rotatable winding-and-setting stem, of an operating-lever normally connected at its upper end with the said stem, a stud on which the said lever is mounted and which is counterbored and threaded at its rear end, and an operating-screw entering the said counterbored and threaded rear end of the stud and passing through the back movement-plate of the watch, whereby by moved bodily forward and disconnected at its upper end from the said stem and drawn bodily rearward and connected with the said stem.

4. In a stem-winding and stem-setting watch, the combination with the windingand-setting stem and yoke thereof, of an operating-lever normally connected with the stem, a locking-lever formed with a notch to receive a portion of the operating-lever when the stem has been pulled outward preparatory to setting the watch, a stud carried by the yoke and engaged by the locking-lever, whereby the yoke is swung from its winding into its setting position, and a spring for the said yoke.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
